And when I'm trying to open document properties for to give Authorization and Assigned DOC CAL its showing processing symbol for several minutes and finally nothing get happen and not showing document properties. If anyone solve the same or having solution please assist me.

Ashfaq is correct, this might be related to bug# 63724 "Invalid character in .pgo files (BorrowedCAL.pgo CALData.pgo) causes QMC not to list properties/ CAL data" . To confirm this you need to go to the QMC logs and check for this error:

This error is cause due to a end user having a bad UUID ( Universal Unique Identifier), for that QMC tries to read the borrowcaldata.pgo but cannot understand the corrupted UUID. TO correct the UUID that a machine / OS issue not Qlikview's so your IT team can help. To find out which user is the trouble one, you can do PGOs as XML ( attached article), look in the borrowcaldata.xml and check all IDs, normally they are numbers only, but if you see weird characters, that might be the trouble one.

You can try to upgrade to V11.20 SR7, it should have a fix where ignores that corrupt UUID.

Anyways, unfortunately the only way to correct this is by recreating the BorrowCalData.pgo which will removed all the assignments.
